Abstract:
As the screen size becomes larger, it is required to make the device achieve higher definition, higher open area ratio, and higher reliability. Further, requirements for improvements in productivity and cost minimization are also increased. In the present invention, a substrate is pasted with a counter substrate after the liquid crystal material 114 is discharged (or dripped) only over a pixel area that is on a pixel electrode provided over a substrate with a large area by ink jet. Further, both of applying a seal material and dripping of a liquid crystal may be performed to the counter substrate. The total amount of liquid crystal use in a manufacturing process is reduced by forming a liquid crystal layer by ink jet.
